diopter
This term is used exclusively within the fields of ophthalmology, optometry, and physics to quantify the refractive power of a lens. It describes how strongly a lens bends light; a higher diopter value indicates a shorter focal length and a more powerful lens.
In clinical settings, the term is often used as a shorthand for the prescription strength of eyeglasses or contact lenses. Positive values indicate converging lenses used for hyperopia (farsightedness), while negative values indicate diverging lenses used for myopia (nearsightedness).
